Abstract

A momentum integral technique has been developed for prediction of two- and three-dimensional turbulent wakes. The analysis is valid for both near and far wakes. The only assumption involved in the analysis is the existence of similarity in velocity profiles/Based on this analysis, a computer program was written to predict the decay characteristics of wake-velocity defect and the variation of wake width downstream of the body. The numerical study includes wakes of a fiat plate, airfoil, cascade of blades, and rotor blades. In all cases, results are in good agreement with experimental data. The simplicity, accuracy, and computational efficiency of this technique makes it very attractive.
